Hello everyone, i would like some advice. I plan on starting up a 55 gallon reef aquarium and have done tons of research and i think i know alot now and im ready to start off with this idea. I dont want to spend a ton of money on a sump so i want to create an internal DIY sump. I want to know if this would work in the chamber, 1) main pump covered with a filter sock and with heater , 2) protein skimmer , 3) refugium with live rock and macro algae , 4) outflow ? Am i missing anything or can i add anything to make this better and also do i need any addittional filtration? Basically the sump would pertrude a good amount just under a 1/3 of the width of the tank covering the whole back. Now on the downside it does make my tank way smaller but i do not plan to house large fish such as tangs anyways i just want soft corals mainly and some LPS corals and a small community like clownfish cardinals and clean a up crew. I also have a T5 high output light and the skimmer is a reef octopus 800. Do i have everything i need (equiptment wise) to start a successful reef? I am new to this hobby and want to make sure i have everything i need to start this off properly.
